WHAT IT DOES

What ea-hydrology.stations.measures does on Apibase

AI agents call ea-hydrology.stations.measures to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`parameter`	string	—	Filter measures by parameter type. Note: TEMPERATURE must be uppercase, the others lowercase — confirmed upstream data quirk, not a typo.
`station_id`	string	Yes	Station identifier — the `station_id` (notation/GUID) returned by ea-hydrology.station_search, e.g. "052d0819-2a32-47df-9b99-c243c9c8235b".

Parameters from the server's own tool schema.

RECOMMENDED RULE

The rule that runs ea-hydrology.stations.measures safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ea-hydrology.stations.measures, this is the rule to start with:

ea-hydrology.stations.measures Allowed

ea-hydrology.stations.measures is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every ea-hydrology.stations.measures call is checked against it from then on.

FAQ

Questions about ea-hydrology.stations.measures

What does the ea-hydrology.stations.measures tool do? +

List the data series (measures) recorded at one EA hydrology station — e.g. 15-minute instantaneous flow, daily mean/min/max level, daily total rainfall — identified by the station_id from ea-hydrology.station_search. Optional parameter filter (flow, level, rainfall, TEMPERATURE — note TEMPERATURE is uppercase upstream). Returns measure_id, period, value type, and unit for each series — use measure_id with ea-hydrology.readings_latest or ea-hydrology.readings_range. Data: environment.data.gov.uk/hydrology, UK Open Government Licence v3.0, no auth required. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.

What parameters does ea-hydrology.stations.measures accept? +

ea-hydrology.stations.measures accepts 2 parameters: parameter, station_id. Required: station_id. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on ea-hydrology.stations.measures? +

Register the Apibase MCP server in PolicyLayer and add a rule for ea-hydrology.stations.measures: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.

What risk level is ea-hydrology.stations.measures? +

ea-hydrology.stations.measures is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit ea-hydrology.stations.measures? +

Yes. Add a rate_limit block to the ea-hydrology.stations.measures rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block ea-hydrology.stations.measures completely? +

Set action: deny in the PolicyLayer policy for ea-hydrology.stations.measures. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides ea-hydrology.stations.measures? +

ea-hydrology.stations.measures is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
